Linux. The PolyServe kernels are available on MatrixLink in the following

binary and source formats:

PolyServe also supplies devel packages for these kernels. The devel

packages contain the kernel header files needed to build a kernel module,

such as for third-party MPIO software. Also available are kdb packages,

which enable the kernel debugger, and the debuginfo package, which

contains the necessary symbols to debug crash dumps.

SLES9 Support

The following operating systems and SLES9 kernels are supported.

You will need to obtain the appropriate kernel from SuSE.

MxFS-Linux Upgrade Information

To prevent unnecessary Virtual NFS Service failovers that can occur when

all NFS server threads are busy, the MxFS-Linux installation now sets the

number of NFS server threads to 32. If you have currently configured a

larger number of NFS server threads, the existing value will not be

changed.

The MxFS-Linux installation also increases the maximum number of

outstanding NFS RPC requests for the TCP network transport and the

UDP network transport to 128. If you have currently set these parameters

to a larger value, that value will not be changed.
